Abstract
The fluorescence excitation spectra of CN(A,B-->X) and CF3 (2A'1-->1A' '2) and the quantum yield for the CN(B) radical formation were measure d in the photodissociation of CF3CN in 105-135 nm. The quantum yield f or the CN(B) radical formation was found to be only a few percent. The similarity in the excitation energy dependence of CN(B-->X) and of CN (A-->X) indicated a common dissociation mechanism via the 3s Rydberg s tate of CF3CN for both states.
